Kim Kardashian, Kylie Jenner Go Braless

Brian Prahl/Splash News

The Kar-Jenner clan has been having the time of their lives in Costa Rica. From helicopter rides to hot tub sessions, they've been making the most of their gorgeous resort, but on Sunday night, the family stepped out for dinner on the town—dressed to the nines, no less.

After spending some time outside of the spotlight, Kim Kardashian West was back to her body-baring ways, donning a sheer metallic Paco Rabanne dress sans bra. The reality star paired the daring look with a navy suede baseball cap and lace-up sandals that snaked around her calves.
